Evaluación del efecto del aditivo ERR y del pH en las membranas líquidas aplicadas (LAM) de Sika Colombia S.A.S y su desempeño a escala laboratorio

The purpose of this degree work was the evaluation of the incorporation of the ERR additive and its interaction with two pH modifiers (MPA and MPH3), in 3 current products that are managed in the portfolio of the sponsoring company performing an experimental design 3 a the 2 in each, for a total of 27 experiments, in order to improve drying times and the evaluation to early resistance to rain. In addition, the performance in physical, chemical and mechanical properties used in the waterproofing industry today was taken into account. The results obtained showed that there is no compatibility of the ERR additive and the MPH3 pH modifier. The results obtained show different percentages of both the pH modifier and the additive in the following way (MPA, ERR Additive): For the current product P1 experiment 3 was selected (4%, 1%), for P2 the experiment was selected 7 (1%, 2%), and for P3 experiment 2 was selected (4%, 1.5%). In comparative with the products of the market (X1, X2 and X3) it was found that those of the competition had low values of mechanical tests after UV aging, high water absorption and high water vapor permeability, decreasing their performance with respect to the selected experiments. In the test of early rain resistance and dry time with respect to the current products, it was reduced between 15 to 30 minutes, favoring its performance compared with the products of the market.
